Description: The CH-47 Chinook is a twin-engine, tandem-rotor, heavy-lift transport helicopter in service with the US Army and other Armed Forces worldwide. It is enabled to transport ground forces, supplies, ammunition, and other battle-critical cargo. In addition, the CH-47 Chinook can be employed for medical evacuation, aircraft recovery, fire fighting, parachute drops, heavy construction, civil development, disaster relief and search and rescue (SAR).

The US Army CH-47F Block II helicopter program is aimed at delivering the next generation Chinook aircraft beginning in 2023. The CH-47F Block II heavy-lift helicopter features increased lifting power and other advancements. An improved drivetrain will transfer greater power from the engines to the all-new, swept-tip Advanced Chinook Rotor Blades, which have been engineered to lift 1,500 additional pounds on their own. The US Army awarded Boeing a $276 million contract for the development of the new Chinook helicopter with the first prototype to be delivered in 2019. The first production Block II helicopter will be delivered in 2023 with roughly more than 500 helicopters to be upgraded to the new standard.
